passage 285 of 596 · Book I. On The Knowledge Of God The Creator. > Chapter VIII. An Exposition Of The Moral Law (22/47)

in brief
Calvin argues against the Anabaptists’ total rejection of oaths by interpreting Christ’s “swear not at all” as forbidding oath forms that violate God’s moral law, not legitimate, necessary oaths permitted or commanded by God.

gods.(855) And the Apostle evidently attests the same, when he says, that “men swear by the greater, but that God, because he could swear by no greater, sware by himself.”(856)

XXVI. The Anabaptists, not satisfied with this limitation of oaths, condemn all oaths without exception; because the prohibition of Christ is general: “I say unto you, Swear not at all. But let your communication be, Yea, yea; Nay, nay: for whatsoever is more than these cometh of evil.”(857) But by this mode of interpretation they set Christ in opposition to the Father, as though he descended into this world to abrogate the Father’s decrees. For in the law the eternal God not only permits an oath, as a lawful thing, which would be sufficient to justify the use of it, but in cases of necessity commands it.(858) Now, Christ asserts, that “he and his Father are one,” that “he acts only according to the commands of the Father,” that “his doctrine is not of himself,” &c.(859) What then? Will they make God to contradict himself, by prohibiting and condemning in our conduct that which he has before approved and enjoined? But as the words of Christ involve some difficulty, let us enter on a brief examination of them. Here we shall never arrive at the truth, unless we attend to the design of Christ, and advert to the subject of which he is there treating. His design is not to relax or to restrict the law, but to reduce it to its true and genuine meaning, which had been very much corrupted by the false comments of the scribes and Pharisees. If we bear this in our minds, we shall not be of opinion that Christ condemned all oaths, but only those which transgress the rule of the law. It appears to have been the custom of the people at that time to avoid nothing but perjuries; whereas the law forbids not only perjuries, but likewise all vain and superfluous oaths. Our Lord, therefore, that infallible expositor of the law, apprizes them that it is sinful, not only to perjure themselves, but even to swear. To swear in what manner? In vain. But the oaths which are sanctioned in the law he leaves without any objection. They consider themselves as urging a very powerful argument, when they violently insist on the particle at all; which, nevertheless, refers not to the word swear, but to the forms of oaths that are there subjoined. For the error there condemned consisted, partly, in a supposition that in swearing by heaven and earth, there was no interference with the name of God. Therefore, after the principal instance of transgression, the Lord goes on to destroy all their subterfuges, that they may not imagine themselves to have escaped by suppressing the name of God, and calling heaven and earth to witness for them. For here, by the way, it must be remarked, that men indirectly swear by God, though his name is not expressed; as when they swear by the light of life, by the bread which they eat, by their baptism, or by any other blessings which they have received from the Divine munificence. Nor does Christ in that place prohibit them from swearing by heaven, and earth, and Jerusalem, in order to correct superstition, as some falsely imagine; but rather to confute the sophistical subtlety of persons who thought there was no crime in the foolish use of indirect oaths, as though they were not chargeable with profaning the sacred name of God, which is engraven, however, on all his benefits. But the case is different, where any mortal man, or one that is dead, or an angel, is substituted in the place of God; as, among idolatrous nations, adulation invented that odious form of swearing by the life or genius of a king; because in such cases the deification of a creature obscures and diminishes the glory of the only true God. But when we mean nothing but to derive a confirmation to our assertions from the sacred name of God, although it be done in an indirect manner, yet all such frivolous oaths are offensive to his majesty. Christ deprives this licentious practice of every vain excuse, by his prohibition of swearing at all. James also aims at the same point,(860) where he uses the language of Christ, which I have cited; because this presumption has always been prevalent in the world, notwithstanding it is a profanation of the name of God. For if you refer the particle at all to the substance of swearing, as though every oath, without exception, were unlawful, what means the explanation which is immediately annexed, “Neither by heaven, neither by earth,” &c., language evidently used in refutation of those cavils, which the Jews considered as furnishing an excuse for their sin.
